How to Make Hearty Slow Cooker Steak and Cheddar Potato Casserole
Sear the Steak: Heat olive oil in a skillet over medium-high heat. Add the steak strips and sear for 2-3 minutes on each side until browned, creating a delicious crust. Remove the steak from the skillet and set aside.

Prepare the First Layer: Layer the bottom of your slow cooker with half of the sliced potatoes. Top with half of the seared steak, followed by the saut ed onions and garlic. Season generously with salt, pepper, paprika, and thyme.
Add the Second Layer: Add another layer of potatoes, then the remaining steak, onions, and garlic. Don t forget to season this layer similarly with salt, pepper, paprika, and thyme for balanced flavor throughout.
Mix the Sauce: In a small bowl, whisk together the sour cream, milk, and beef broth until smooth. Pour this flavorful mixture over the layered ingredients in the slow cooker, ensuring everything is well-coated.
Slow Cook to Perfection: Cover your slow cooker and cook on low for 6-7 hours. You ll know it s done when the potatoes are tender and the house is filled with mouthwatering aromas.
Melt the Cheese: About 30 minutes before serving, sprinkle the shredded cheddar cheese evenly over the casserole. Cover and cook for the remaining time until the cheese is melted and bubbly, creating a deliciously gooey topping.

Expert Tips for Hearty Slow Cooker Steak and Cheddar Potato Casserole
Quality Steak Matters: Choose fresh sirloin or ribeye for a more tender and flavorful casserole. Avoid using tougher cuts that won t soften as well.
Slice Potatoes Thinly: Ensure even cooking by slicing the russet potatoes about 1/8 inch thick. Thick slices may remain firm while the other layers are tender.
Layering Technique: Layer ingredients evenly and season each layer to build flavor. This keeps the taste consistent throughout your Hearty Slow Cooker Steak and Cheddar Potato Casserole.
Cooking Time Awareness: Cooking times can vary by slow cooker model; check for tenderness after 5-6 hours and adjust as needed to avoid mushy potatoes.
Cheese Timing: Add cheese 30 minutes before serving for the best melt. If added too early, it may become rubbery as it overcooks.
